I have the equation q=mcdeltat
How do I solve for m or c or deltat?
Anyone remember that process?

divide both sides by whatever you don't want.

if you want delta t then you don't want m or c so:

$q=mc \Delta t$

$\frac{q}{mc} = \frac{mc \Delta t}{mc}$

cancelling:

$\frac{q}{mc} = \Delta t$

like so.

With other formulae where the things you don't want are on the bottom, you have to multiply both sides by them, you can see what you're aiming to achieve though.

Just remember you have to do the same thing to both sides and apply basic arithmetic and you can't go wrong :)
